Integrations

Protecto integrations

Protecto sits between your data and the AI models that use it. It works with major LLM providers including OpenAI, Google Gemini, Anthropic Claude, DeepSeek, Cohere, and Grok, so prompts and responses can be scanned and masked before data leaves your control. Developers can add it to AI applications built with LangChain, LlamaIndex, Semantic Kernel, and Haystack. For retrieval pipelines, it connects to PostgreSQL, MongoDB, and vector stores such as Pinecone and Weaviate. Identity integrations with Active Directory and Okta drive context-based access decisions. Protecto runs as SaaS, inside a customer VPC, or fully on-premise, including air-gapped environments.
